Description

Technical Field

[0001] This utility model relates to the field of electrolyte injection technology, specifically to an automatic electrolyte injection machine for capacitors. Background Technology

[0002] A capacitor is an electronic component used to store electrical charge and energy. Its core structure consists of two conductors (plates) placed close to each other and an insulating medium (such as ceramic, plastic or electrolyte) in between.

[0003] During the manufacturing process of capacitors, an automatic electrolyte injection machine is required to inject electrolyte into the capacitor. However, in most automatic electrolyte injection machines, the electrolyte may be left to stand during use. This standing may cause uneven concentration distribution. Directly injecting the electrolyte into the capacitor will affect the quality of the capacitor in later use.

[0004] Therefore, an automatic capacitor electrolyte injection machine is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic capacitor electrolyte injection machine in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution: An automatic capacitor electrolyte injection machine includes a worktable, a fixed frame at the bottom of the worktable, a moving mechanism for lateral movement on the fixed frame, a positioning template slidably mounted on the moving mechanism, and a fixing mechanism for locking the positioning template in place on the moving mechanism. A fixed frame is mounted on the top of the worktable, and a stirring mechanism for stirring the electrolyte to prevent uneven concentration distribution is mounted on the top of the fixed frame. A cylinder is mounted on the surface of the fixed frame, and a connecting frame is mounted on the telescopic end of the cylinder. An injection head is mounted on the connecting frame. A metering pump is mounted on the surface of the fixed frame, and the metering pump is connected to the stirring mechanism via a pipeline. The injection head is connected to the metering pump via a pipeline. A controller is mounted on the top of the worktable.

[0007] Furthermore, the moving mechanism includes a screw, which is rotatably mounted inside the fixed frame. A movable seat is threaded onto the outer wall of the screw, and the movable seat is slidably mounted on the worktable and the fixed frame. A servo motor is fixedly mounted on the surface of the fixed frame, and the screw is fixedly mounted on the output end of the servo motor.

[0008] Furthermore, two telescopic dust covers are fixedly installed inside the fixed frame, and the two telescopic dust covers are respectively fixedly installed on both sides of the movable seat, with screws located inside the two telescopic dust covers.

[0009] Furthermore, the fixing mechanism includes two fixing shells, which are fixedly installed on the surface of the movable seat. The top of the movable seat is provided with a positioning groove, and the positioning template is slidably installed on the inner wall of the positioning groove. Insert blocks are slidably installed on the inner walls of both fixing shells, and the insert blocks are slidably installed on the positioning template. T-shaped studs are threadedly installed on both fixing shells, and the T-shaped studs are rotatably installed on the insert blocks. Knobs are fixedly installed on the surface of both T-shaped studs.

[0010] Furthermore, the stirring mechanism includes a stirring tank, which is fixedly installed on the top of the fixed frame. A metering pump is connected to the stirring tank via a pipeline.

[0012] The beneficial effects of this utility model are as follows: This invention, through the arrangement of a positioning template, a fixing mechanism, and a stirring mechanism, allows for the following process: A positioning template compatible with the capacitor is selected and placed on a moving mechanism, then locked in place by the fixing mechanism. The capacitor is then placed sequentially within the positioning template. The controller activates the stirring mechanism to stir the electrolyte, ensuring thorough mixing of its components and preventing uneven concentration distribution. The controller then activates the moving mechanism to move the positioning template and fixing mechanism forward, positioning the capacitor below the injection head. The controller then activates a cylinder to insert the injection head into the capacitor. Finally, the controller controls the... The metering pump is started to draw a quantitative amount of electrolyte from the stirring mechanism and deliver it to the injection head, which then injects it into the capacitor. After the first capacitor is injected, the controller controls the cylinder and moving mechanism to reset the injection head. The positioning template, fixing mechanism, and capacitor continue to move forward, and the second capacitor replaces the first capacitor to continue the injection operation. This allows for easy selection and installation of a positioning template that matches the shape of the capacitor, enabling the positioning of multiple capacitors, improving flexibility, adjusting the position of the positioning template, and stirring and mixing the electrolyte to avoid uneven concentration distribution that could affect the electrolyte performance.

[0020] like Figure 1-3 As shown, an automatic capacitor electrolyte injection machine includes a worktable 1, a fixed frame 2 at the bottom of the worktable 1, and a moving mechanism 3 for lateral movement on the fixed frame 2; as shown... Figure 1-3 As shown, specifically, the moving mechanism 3 includes a screw 301, which is rotatably installed inside the fixed frame 2. A moving seat 302 is threaded onto the outer wall of the screw 301, and the moving seat 302 is slidably installed on the worktable 1 and the fixed frame 2. A servo motor 304 is fixedly installed on the surface of the fixed frame 2, and the screw 301 is fixedly installed at the output end of the servo motor 304. Two telescopic dust covers 303 are fixedly installed inside the fixed frame 2, and the two telescopic dust covers 303 are respectively fixedly installed on both sides of the moving seat 302. The screw 301 is located inside the two telescopic dust covers 303.

[0021] More specifically, by setting up the telescopic dust cover 303, dust can be prevented from adhering to the outer wall of the screw 301 and affecting its transmission. The servo motor 304 is started, which drives the screw 301 to rotate, so that the moving seat 302 moves laterally within the limits of the worktable 1 and the fixed frame 2. The two telescopic dust covers 303 move along the stretching and contracting trajectories respectively, thereby adjusting the position of the moving seat 302.

[0022] A positioning template 5 is slidably mounted on the moving mechanism 3, and a fixing mechanism 6 is provided on the moving mechanism 3 for inserting and locking the positioning template 5; for example Figure 1-3 As shown, specifically, the fixing mechanism 6 includes two fixing shells 601, which are fixedly installed on the surface of the movable seat 302. The top of the movable seat 302 is provided with a positioning groove, and the positioning template 5 is slidably installed on the inner wall of the positioning groove. Insert blocks 602 are slidably installed on the inner walls of both fixing shells 601, and the insert blocks 602 are slidably installed on the positioning template 5. T-shaped studs 603 are threadedly installed on both fixing shells 601, and the T-shaped studs 603 are rotatably installed on the insert blocks 602. Knobs 604 are fixedly installed on the surface of both T-shaped studs 603.

[0023] More specifically, by placing the positioning template 5 in the positioning groove, and then turning the knob 604, the T-shaped stud 603 is rotated and moved laterally, pushing the insert block 602 to slide in the fixed shell 601 and insert it into the positioning template 5, thereby locking it in place, which facilitates the installation and fixing of the positioning template 5.

[0024] A fixed frame 4 is provided on the top of the workbench 1. A stirring mechanism 7 for stirring the electrolyte to prevent uneven concentration distribution is provided on the top of the fixed frame 4. A cylinder 9 is provided on the surface of the fixed frame 4. A connecting frame 10 is provided at the telescopic end of the cylinder 9. An injection head 11 is provided on the connecting frame 10. A metering pump 8 is provided on the surface of the fixed frame 4, and the metering pump 8 is connected to the stirring mechanism 7 via a pipe. The injection head 11 is connected to the metering pump 8 via a pipe. A controller 12 is provided on the top of the workbench 1. Figure 3 As shown, specifically, the stirring mechanism 7 includes a stirring tank 701, which is fixedly installed on the top of the fixing frame 4. The metering pump 8 is connected to the stirring tank 701 by a pipeline. A tank cover 702 is slidably installed on the outer wall of the stirring tank 701. A sealing gasket is fixedly installed on the tank cover 702 and is in contact with the stirring tank 701. The stirring tank 701 and the tank cover 702 are fixedly connected by bolts. A feeding hopper 707 is provided on the tank cover 702. A second servo motor 706 is fixedly installed on the top of the tank cover 702. A shaft column 703 is fixedly installed at the output end of the second servo motor 706. Three sets of stirring rods 704 are fixedly installed on the outer wall of the shaft column 703. Three scrapers 705 are fixedly installed on the three sets of stirring rods 704 and are in contact with the inner wall of the stirring tank 701.

[0025] More specifically, electrolyte is injected into the mixing tank 701 through the feeding hopper 707. The servo motor 706 is started, driving the shaft 703 to rotate. The three sets of stirring rods 704 and three scrapers 705 rotate to stir the electrolyte, avoiding uneven concentration distribution caused by standing. The three scrapers 705 scrape the walls of the mixing tank 701 to prevent a small amount of electrolyte from sticking to the inner wall of the mixing tank 701 and affecting the mixing quality. Since the mixing tank 701 and the tank cover 702 are fixedly connected by bolts, they can be disassembled for cleaning and maintenance. The sealing gasket enhances the sealing between the mixing tank 701 and the tank cover 702, preventing electrolyte leakage from the gap between the mixing tank 701 and the tank cover 702.

[0026] In summary, the positioning template 5 consists of a fixed plate and multiple positioning slots. These slots are adapted to the capacitors, and placing the capacitors within them prevents displacement during the electrolyte injection process. In use, a positioning template 5 compatible with the capacitor is selected and placed on the moving mechanism 3. The fixing mechanism 6 then locks and connects the template. The capacitors are then placed sequentially within the positioning template 5. The controller 12 activates the stirring mechanism 7 to stir the electrolyte, ensuring thorough mixing of its components and preventing uneven concentration distribution. The controller 12 then activates the moving mechanism 3 to move the positioning template 5 and fixing mechanism 6 forward, positioning the capacitors below the injection head 11. Finally, the controller 12 activates the cylinder 9 to... The injection head 11 enters the capacitor, and then the metering pump 8 is started by the controller 12 to quantitatively extract and deliver the electrolyte from the stirring mechanism 7 to the injection head 11, which is then injected into the capacitor. After the first capacitor is injected, the cylinder 9 and the moving mechanism 3 are controlled by the controller 12 to reset the injection head 11. The positioning template 5, the fixing mechanism 6, and the capacitor continue to move forward, and the second capacitor replaces the position of the first capacitor to continue the injection operation. This allows for easy selection and installation of the positioning template 5 to match the shape of the capacitor, positioning of multiple capacitors, improved flexibility, adjustment of the position of the positioning template 5, and stirring and mixing of the electrolyte to avoid uneven concentration distribution that could affect the performance of the electrolyte.
